Chrysanthemum plant named ‘Dochrysbumb’

ABSTRACT

A new and distinct cultivar of  Chrysanthemum  plant named ‘Dochrysbumb’, characterized by its upright to somewhat outwardly spreading and uniformly and mounded plant habit; moderately vigorous growth habit; freely branching habit; dense and full plant form; uniform and freely flowering habit; medium-sized to large decorative-type inflorescences with dark yellow-colored ray florets; freely and early flower habit; and good postproduction longevity.

Botanical designation: Chrysanthemum X morifolium.

Cultivar denomination: ‘DOCHRYSBUMB’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct Chrysanthemum plant, botanically known as Chrysanthemum X morifolium, commercially grown as a potted Chrysanthemum plant and hereinafter referred to by the name ‘Dochrysbumb’.

The new Chrysanthemum plant is a product of a planned breeding program conducted by the Inventor in Fareham, Hampshire, United Kingdom. The objective of the breeding program is to create new potted Chrysanthemum plants with numerous attractive inflorescences.

The new Chrysanthemum plant originated from a cross-pollination made in January, 2014 by the Inventor in Fareham, Hampshire, United Kingdom of a proprietary selection of Chrysanthemum X morifolium identified as code number 807825, not patented, as the female, or seed, parent with a proprietary selection of Chrysanthemum X morifolium identified as code number 807744, not patented, as the male, or pollen, parent. The new Chrysanthemum plant was discovered and selected by the Inventor as a single flowering plant from within the progeny of the stated cross-pollination in a controlled greenhouse environment in Fareham, Hampshire, United Kingdom in September, 2014.

Asexual reproduction of the new Chrysanthemum plant by terminal vegetative cuttings was first conducted in Fareham, Hampshire, United Kingdom in December, 2014. Asexual reproduction by terminal vegetative cuttings has shown that the unique features of this new Chrysanthemum plant are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

Plants of the new Chrysanthemum have not been observed under all possible combinations of environmental conditions and cultural practices. The phenotype may vary somewhat with variations in environmental conditions such as temperature, daylength and light intensity, without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Dochrysbumb’. These characteristics in combination distinguish ‘Dochrysbumb’ as a new and distinct Chrysanthemum plant:

-   -   1. Upright to somewhat outwardly spreading and uniformly and         mounded plant habit.     -   2. Moderately vigorous growth habit.     -   3. Freely branching habit; dense and full plant form.     -   4. Uniform and freely flowering habit.     -   5. Medium-sized to large decorative-type inflorescences with         dark yellow-colored ray florets.     -   6. Freely and early flower habit.     -   7. Good postproduction longevity.

Plants of the new Chrysanthemum can be compared to plants of the female parent selection. Plants of the new Chrysanthemum differ primarily from plants of the female parent selection in the following characteristics:

-   -   1. Plants of the new Chrysanthemum have larger inflorescences         than plants of the female parent selection.     -   2. Ray florets of plants of the new Chrysanthemum are darker         yellow in color than ray florets of plants of the female parent         selection.

Plants of the new Chrysanthemum can be compared to plants of the male parent selection. Plants of the new Chrysanthemum differ primarily from plants of the male parent selection in the following characteristics:

-   -   1. Plants of the new Chrysanthemum are taller than plants of the         male parent selection.     -   2. Plants of the new Chrysanthemum and the male parent selection         differ in ray floret color as plants of the new Chrysanthemum         have inflorescences with dark yellow-colored ray florets whereas         plants of the male parent selection have inflorescences with         bronze-colored ray florets.

Plants of the new Chrysanthemum can also be compared to plants of Chrysanthemum X morifolium ‘Fichrysun’, not patented. In side-by-side comparisons, plants of the new Chrysanthemum differ primarily from plants of ‘Fichrysun’ in the following characteristics:

-   -   1. Plants of the new Chrysanthemum flower earlier than plants of         ‘Fichrysun’.     -   2. Plants of the new Chrysanthemum have larger inflorescences         than plants of ‘Fichrysun’.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photograph and following observations and measurements describe plants grown during the spring in 15.25-cm containers in a polyethylene-covered greenhouse in Encinitas, Calif. and under cultural practices typical of commercial potted Chrysanthemum production. During the production of the plants, day temperatures averaged 26° C., night temperatures averaged 20° C. and light levels averaged 4,500 lux. Plants were propagated under long day/short night conditions and then grown under short day/long night conditions to induce inflorescence initiation and development. Plants were disbudded. Five plants were grown per pot and plants were 14 weeks old when the photographs and detailed description were taken. In the following description, color references are made to The Royal Horticultural Society Colour Chart, 2015 Sixth Edition, except where general terms of ordinary dictionary significance are used.
